VIIILIAM PIERPONT, OF SALEM, NEW JERSEY.

IMPROVEMENT IN HORSE-POWERS.

Specilication forming part ot' Letters Patent No. 37,178, dated December 16, 1862.

T0 all whom, it may concern:

Beit known that 1', WILLIAM PIERPoN'I. ot" Salem, in the county of Salem and State of New Jersey, have invented certain new and useful Improvementsin Horse-Powers; and I do hereby declare that the following' is a full, clear, and exact description ot' the same, ret'- erence being had to the accompanying dra-W- ings, forming a part ot' this specification, and in Which- Figure 1 represents a perspective view of the main Wheel oi' a horse-power with my improvements applied thereto, and Fig. 2 represents a section ot' a part only given to show more fully the yielding nature ot the draftlevers.

In the drawings, A represents the main Wheel, having socket a cast on its Lipper side to receive the rear ends ot' the draft-levers B B B B. On t-he inner side ot'tlie socket-pieces c are cast lever-supporting projections b. The rear ends of the draftlevers B are fitted to Work loosely in the socket-pieces a, as indicated in the drawings, the rear end ot1 one lever projecting sufliciently far through its socket-piece to the lever back of it. The levers B are connected together by braces O, the front ends ot' the latter beingl fastened by loose bolts c and the rear ends by hinges or pivots cl. l By the above mode of construction, when the horses are attached to the ends ot' the ,i

draft-levers B by the hooks e and the machine is in operation, the levers B can rise and fall independent of each other and the main Wheel and yet not be liable to break, owing to the Inode of bracing adopted. Again, if it is desired to elevate one lever With its braces for any purpose, it can be done Without removing a bolt. (See Fig. 2.)

The power being applied entirely to the periphery of the wheel in connection with the free and independent action of the levers enables the machine to be operated with much less friction and strain on the gearing and trame. The parts are easily detached and as easily connected togetheragain, which renders it very convenient machine for common use aside from the advantages above alluded to.

Havingdescribed my improved horse-power, what I claim therein as new, and desire to secure by Letters Patent, is-

l. The combination ot' the socket-pieces a. and lever-supporting pieces b With the Inain Wheel A, substantially as and for the purposes set forth.

2. The combination ot1 the draitlevers B with the braces G and main wheel A, substantially as set forth.
